BRICK OR B RIQUET MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 725,690, dated April 21, 1903.

Application filed December 2, 1902. Serial No. 133,617- (No model.) i

To all whom it may cancer-m Be it known that we, JOSEPH WELLINGTON FERGUSON and GEORGE WELSH FERGUSON, subjects of the King of Great Britain and Ire land, residing at Sydney road,.Wangaratta, in the county of Delatite, State of Victoria, Commonwealth of Australia, have invented certain new and useful Improvements in Brick or BriquetMakin'g Machines, of which the following is a specification.

The object of our invention is to provide a cheap and eflective machine for making bricks, briquets, or similar articles. In the past some of the machinery so constructed has been expensive in first cost and also in maintenance; but with our invention the initial expense is not great and the outlay for maintenance but trifling.

In order that our invention may be better understood, we will now refer to the accompanying sheet of drawings, which are to be taken as part of this specification and read herewith.

Figure 1 represents a perspective View looked at from the top of the feeding side.

, Two arrows side by side show the brick-discharge on front of the machine. The clutch, hereinafter described, is in gear with the ejecting-crank, and the eccentric strikingface on the crank is striking the clutch-lever and forcing the said lever onto the round on the fork-arm, and thereby throwing the clutch out of gear. The connecting-rod is toward the machine-front and the tappet out of gear with the ratchet-wheel. 'Fig. 2 shows a perspective view looking from above the brickdischarge corner near the machine-front. A

piece of the exuding mold has just been cut. The clutch-lever, hereinafter described, has been struck by the tappet and thrown the clutch into gear with the crank. The cutter is below the shaping-passage, and the spring which forces the connecting-rod toward the front end of the machine, because the tappet is released from. the ratchet-wheel, is just about to force the said connecting-rod to the machine-front.

Similar letters of reference indicate similar or corresponding parts where they occur in both views.

Our invention includes a main shaft A,

' driven by a pulley or other means. On this is a toothed wheel 0, driving an intermediate Wheel D, rotating upon a stud E. This intermediate wheel drives a toothed wheel F,

secured upon the worm-shaft G. This wormshaft G rotates 'within a barrel H, having liners and at the top a hopper J. Upon the shaft G is the worm K, which forces the material entering the hopper J into the shapingpassage L. Near its outer end holes are made in the side walls of this shaping-passage. These are surrounded by a sand-box 0. Above the end of the shaping-passage, which has liners therein, is situated a cutter M. The arm of this is intermediately pivoted to the pivot-pin N, and its back end, which is overbalanced, rests upon the rocking shaft 0. The pivot-pin N is attached to the-moving end of the cutter-lever P, the inner end of which is attached to the rocking shaft 0. The said rocking shaft 0 is operated by a lever Q, to the outer end of which is attached one end (the lever end) of a connecting-rod R. The other end extends above the main driving-shaft and is then bentdownwardly in the form of a tappet or catch S. The tappet end of the rod has a backward and a forward motion and a side motion. Its forward motion is effected by-the spring W and its backward motion by the teeth upon the ratchet-wheel V. The side motion to the tappet is imparted by a link X, one end of which is pivoted to the said connecting-rod and the other pivoted-to the end Y of a lever. This lever is pivoted near its middle to a pillar Z, and near its other end Y is secured a tongue-spring A, which forces the said end Y toward the shaping-passage. Near the end of the said lever Y and facing the shaping-passage is secured or pivoted a strikingplate B.

Near the middle of the connecting-rod R is a depending stud T, which stud as the rod reciprocates bears against the hopperside of a short vertical rib or guide U, secured to the frame. This rib keeps the tappet S on the rod R in contact with the recesses in the aforesaid ratchet-wheel Vwhile the said connecting-rod is moving backwardly. When the stud T passes the back end of the rib U, the tongue spring A (hereinbefore described) acts and draws the connecting-rod and tappet to the press-box.

Beneath the cutter M is situated the month of the press-box D- This press-box is rectangular in section and in width equals the length of the brick and in height thewidth of the said brick. Sliding backward and forward within the said press-box is the ram E. This has pivoted to it one end of a pitman F. The other end of this rod is pivoted to an ejecting-crank G. This crank is loose upon the shaft A and though incapable of longitudi-- nal movement on the said shaft is caused to rotate therewith by a clutch or sleeve H. This clutch H has a circumferential groove J around it, and it is capable of moving longitudinally upon the square or keyed portion K of the shaft A. The said clutch H has protuberances L upon its meeting face, which engage in suitable recesses on the meeting face of the loose crank G. The said clutch is moved backward and forward by a fork M on the arm M This arm has a rounded portion M thereon, and its rear end is pivoted to a pillar N. Pivoted to the pillar O is a clutchlever, the crank end P of which has a strikin g-surface on its end. This striking-surface is struck by an eccentric striking-surface R upon the onterend of the crank G. Below the crank endP of the clutch-lever is situated a vertical recess or mouth Z. This embraces the round M on the arm M and when the said lever is forced outwardly by the crank the clutch by the fork is moved out of the ear and the crank remains loose. The clutch is thrown into gear by the tappet S, which strikes the tappet end S of the clutch-lever. I

At the back of the shaping-passage is the partition hopper T. Down this, between each mold, is dropped a partition or distance piece.

The cycle of operation is as follows: The material after having passed through grinding-rollers (situated in any suitable position) and in a plastic or semiplastic state falls into the hopper J. It is then by the worm forced through the shaping-passage L. As the top and bottom of the brick passes the holes in the side walls of the said. shaping-passage some of the sand in the box 0 adheres to the plastic material. This material continues exuding until its outer end strikes the strikingplate B. This plate forces the lever Y outwardly from the machine against the spring .A', and the lever Y by the link X forces the tappet S on the connecting-rod B into one of the teeth of the rotating ratchet-wheel V. It is retained in gear by the stud T bearing against the hopper side of the guide U, and when it has passed the same the spring A pulls it to its normal position. The connecting-rod is then drawn backwardly, and with it the lever Q, which turns the rocking shaft and depresses the cutter-lever P. As the lever P descends so does the cutter M, and the clayis cut off and falls into the mouth of the off and requires ejection.

press-box D. A partition is then dropped into thehopper, and the crank G, which is one behind the other-with a partition between each and are ejected one at a time. The ejecting-crank continues rotating till its strikingsurface R strikes the clutch lever P and throws the clutch out of gear with the crank.

The said crank then falls and rests upon a spring-tongue or other withdrawable rest A andremainsthere till further material is out The clutch is again engaged with the crank by the tappet S striking the tappet end S of the clutch-lever.

Having now described our inv entio n ,-what we claim as new, and desire to secure by Letters Patent, is:- I I I i 1.
